Cleaning a dog’s ear is not an easy task due to which it is avoided by many pet parents. However, this is not the right thing to do. Not maintaining the hygiene of a dog’s ear leads to yeast overgrowth and infection.

Here through this blog, we will let you know everything about what yeast ear infection is, its causes, treatment and ways to prevent it.

Causes of Yeast Ear Infection in Dog

Malassezia pachydermatis is a species of yeast that overgrows in a dog’s ear canal and results in irritation and inflammation. Due to this yeast overgrowth dog suffers from yeast ear infection[1].

Here are some reasons behind yeast overgrowth:

  • If while bathing, swimming or playing with water the water enters the dog’s ear then the yeast overgrows. If the ear is not dried properly the moisture is retained which leads to yeast growth and ear infection in dogs.
  • Allergies or food reactions can cause yeast overgrowth in dogs.
  • Ear mites are conditions in a dog which cause itching and irritation in the dog’s ear. It is spread through coming in contact with an infected dog. These ear mites create a favourable environment for the yeast to grow leading to yeast infection.
  • Poor hygiene, and not cleaning your dog’s ear on a regular basis can result in dirt and debris. Yeast tends to grow in such unhygienic environments easily.
  • Yeast overgrowth can also be caused due to hormonal imbalances and health conditions. Conditions like Cushing’s disease, diabetes or hypothyroidism can also lead to yeast ear infections in dogs.
As mentioned by Leigh Burkett, DVM in petmd, "Yeast are spore-producing fungi that are always present on a dog’s skin, usually in low numbers, as part of the normal flora. A yeast infection happens when there’s an excessive amount of yeast in a certain area."

This procedure is also used for the diagnosis of bacteria and mites.


Cytology is the scientific study of cells it helps in the diagnosis of infections, cancer or genetic disorders. In this process, a vet collects the sample with a special dye and observes it under the microscope.

With this process, it becomes easy for the vet to diagnose the yeast ear infection. Through this process the differentiation between yeast and other cells becomes easy.


Through this process, the vet collects the sample of the ear wax on a culture medium and incubates it for a few days. The collected sample is then isolated which helps the yeast to grow. This cultural process is used to identify the severity of the infection and its sensitivity.
